K31
The Karabiner Modell 1931 (K. 31/Kar. 31/Mq. 31) is a magazine (firearm), magazine-fed, Bolt action#Straight pull, straight-pull bolt-action rifle. It was the standard issue rifle of the Military of Switzerland, Swiss armed forces from 1933 until 1958 though examples remained in service into the 1970s. It has a 6-round removable magazine, and is chambered for the 7.5×55mm Swiss ''Gewehrpatrone 1911'' or GP 11, a cartridge with ballistic qualities similar to the 7.62×51mm NATO/.308 Winchester cartridge. Each rifle included a 6-round detachable box magazine with matching stamped serial number. A stripper clip can be used to load the magazine from the top of the receiver. The Karabiner Modell 1931 replaced both the Schmidt–Rubin#Model 1911 Rifle, Model 1911 rifle and carbine and was gradually replaced by the Stgw 57 from 1958 onwards. Although the K. 31/Kar. 31 is a straight-pull carbine broadly based on previous Swiss "Schmidt–Rubin" service rifles and carbines, the K. 31/Kar ...

Schmidt–Rubin
The Schmidt–Rubin rifles were a series of Swiss Army service rifles in use between 1889 and 1958. They are distinguished by the straight-pull bolt action invented by Rudolf Schmidt and use Eduard Rubin's 7.5×55mm Schmidt–Rubin rifle cartridge. Models Schmidt–Rubin 1889 The Model 1889 was the first in the series of Schmidt–Rubin rifles which served Switzerland from 1889 to 1953. The rifle takes its name from the designer of its action, Colonel Rudolf Schmidt, and the designer of its ammunition, Colonel Eduard Rubin. Production of the rifle began in 1891. The straight-pull bolt action allows the user to pull the bolt straight back to unlock the action, cock the striker, extract, and eject the spent cartridge in one motion, and then push the bolt forward to chamber a round and lock the action. This is as opposed to a traditional bolt action, wherein the user must lift the bolt handle to unlock the action before pulling the bolt back. The rifle is roughly musket length wit ...

Adolf Furrer
Adolf Furrer (born Johann Adolf Furrer-Kägi, November 13, 1873 – January 15, 1958) was a Swiss military officer and small arms designer. He used to be the director of the Waffenfabrik Bern and held the rank of Oberstbrigadier (Chief Brigadier) in the Swiss Army. Adolf Furrer was involved with numerous firearms designs in the Swiss Army's arsenal in the first half of 20th century. He is most well known for the Furrer MP41/44 submachine gun that Swiss Army adopted during World War II, thanks to passionate lobbying of Swiss Army officials. The Furrer MP41/44 would become regarded as one of the worst firearm designs of World War II and history.Chris McNab, Modern Small Arms - 300 of the World's Greatest Small Arms (2018), Amber Books Ltd, Background Johann Adolf Furrer-Kägi was born in November 13, 1873 in Zürich, Switzerland.

Iron Sights
Iron sights are a system of physical alignment markers (usually made of metallic material) used as a sighting device to assist the accurate aiming of ranged weapons (such as a firearm, airgun, crossbow or even compound bow), or less commonly as a primitive finder sight for optical telescopes. The earliest sighting device, it relies completely on the viewer's naked eye (mostly under ambient lighting), and is distinctly different to optical sights such as telescopic sights, reflector (reflex) sights, holographic sights and laser sights, which make use of optical manipulation and/or active illumination, as well as the newer optoelectronics, which use digital imaging and even incorporate augmented reality. Iron sights are typically composed of two components mounted perpendicularly above the weapon's bore axis: a rear sight nearer (or ''proximally'') to the shooter's eye, and a front sight farther forward (or ''distally'') near the muzzle. During aiming, the shooter aligns h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bolt (firearm)
A bolt is the part of a repeating, breechloading firearm that blocks the rear opening (breech) of the barrel chamber while the propellant burns, and moves back and forward to facilitate loading/unloading of cartridges from the magazine. The firing pin and extractor are often integral parts of the bolt. The terms "breechblock" and "bolt" are often used interchangeably or without a clear distinction, though usually, a bolt is a type of breechblock that has a nominally circular cross-section. In most automatic firearms that use delayed blowback, recoil or gas operation, the bolt itself is housed within the larger bolt carrier group (BCG), which contains additional parts that receives rearward push from a gas tube (direct impingement) or a piston system. The slide of a self-loading pistol can be considered a bolt carrier, as it contains the same components and serves the same functions.

Stgw 57
The Sturmgewehr 57 is a selective fire battle rifle designed by Schweizerische Industrie Gesellschaft (now SAN Swiss Arms) of Switzerland. It uses a roller-delayed blowback system similar to the H&K G3 and CETME rifles. The AM 55 entered service in the Swiss Army with the designation F. ass. 57 7.5mm (French/Italian, for ''Fusil d'Assaut/Fucile d'Assalto 1957'') or 7.5mm Stgw. 57 (German for ''Sturmgewehr 1957''), with export variations constituting the SG 510 family of small arms. The Sturmgewehr 57 was adopted for Swiss military service in 1957 and replaced in 1990 by the lighter SIG SG 550 assault rifle, although some reservists used it for several more years. Design details The Stgw. 57 was developed during the late 1950s, internally named AM 55 at SIG. During its development, Rudolf Amsler was the principal designer at Schweizerische Industrie Gesellschaft. It is a selective fire rifle that employs a roller-delayed blowback operating system. The Stgw. 57 was used by th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rifle
A rifle is a long-barreled firearm designed for accurate shooting, with a barrel that has a helical pattern of grooves ( rifling) cut into the bore wall. In keeping with their focus on accuracy, rifles are typically designed to be held with both hands and braced firmly against the shooter's shoulder via a buttstock for stability during shooting. Rifles are used extensively in warfare, law enforcement, hunting, shooting sports, and crime. The term was originally ''rifled gun'', with the verb ''rifle'' referring to the early modern machining process of creating groovings with cutting tools. By the 20th century, the weapon had become so common that the modern noun ''rifle'' is now often used for any long-shaped handheld ranged weapon designed for well-aimed discharge activated by a trigger (e.g., personnel halting and stimulation response rifle, which is actually a laser dazzler). Like all typical firearms, a rifle's projectile (bullet) is propelled by the contained def ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eduard Rubin
Eduard Alexander Rubin (17 July 1846 – 6 July 1920) was a Swiss mechanical engineer who is most notable for having invented the full metal jacket bullet in 1882. His most famous cartridge was the 7.5×55mm Swiss which was the standard ammunition for the Schmidt–Rubin, K31 and Stgw 57 military rifles. Besides the full metal jacket bullet, Rubin developed the military Schmidt-Rubin rifle (together with Rudolf Schmidt), the Rubin-Fornerod ignition mechanism and the use of TNT and ammonium nitrate to replace gunpowder in artillery grenades. His fully copper clad bullets were also the inspiration for the full metal jacket bullets introduced in 1886 for the Lebel rifle. He served as director of the Swiss Federal Ammunition Factory and Research Center in Thun. He held the rank of colonel in the Swiss military The Swiss Armed Forces (german: Schweizer Armee, french: Armée suisse, it, Esercito svizzero, rm, Armada svizra; ) operates on land and in the air, serving as ...

Twist Rate
In firearms, rifling is machining helical grooves into the internal (bore) surface of a gun's barrel for the purpose of exerting torque and thus imparting a spin to a projectile around its longitudinal axis during shooting to stabilize the projectile longitudinally by conservation of angular momentum, improving its aerodynamic stability and accuracy over smoothbore designs. Rifling is characterized by its twist rate, which indicates the distance the rifling takes to complete one full revolution, such as "1 turn in 10 inches" (1:10 inches), "1 turn in 254 mm" ("1:254 mm" or "1:25.4 cm)", or the like. Normally, an experienced shooter can infer the units of measurement from the numbers alone. A shorter distance indicates a faster twist, meaning that for a given velocity the projectile will rotate at a higher spin rate. The combination of length, weight, and shape of a projectile determines the twist rate needed to gyroscopically stabilize it – barrel ...

Bolt Action
Bolt-action is a type of manual firearm action that is operated by ''directly'' manipulating the bolt via a bolt handle, which is most commonly placed on the right-hand side of the weapon (as most users are right-handed). Most bolt-action firearms use a rotating bolt design, where the handle must first be rotated upward to unlock the bolt from the receiver, then pulled back to open the breech and allowing any spent cartridge case to be extracted and ejected. This also cocks the striker within the bolt (either on opening or closing of the bolt depending on the gun design) and engages it against the sear. When the bolt is returned to the forward position, a new cartridge (if available) is pushed out of the magazine and into the barrel chamber, and finally the breech is closed tight by rotating the handle down so the bolt head relocks on the receiver. Bolt-action firearms are generally repeating firearms, but some single-shot breechloaders also use bolt-action design as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stock (firearm)
A gunstock or often simply stock, the back portion of which is also known as a shoulder stock, a buttstock or simply a butt, is a part of a long gun that provides structural support, to which the barrel, action, and firing mechanism are attached. The stock also provides a means for the shooter to firmly brace the gun and easily aim with stability by being held against the user's shoulder when shooting the gun, and helps to counter muzzle rise by transmitting recoil straight into the shooter's body. The tiller of a crossbow is functionally the equivalent of the stock on a gun. History and etymology The term stock in reference to firearms dates to 1571 is derived from the Germanic word ''Stock'', meaning tree trunk, referring to the wooden nature of the gunstock. Early hand cannons used a simple stick fitted into a socket in the breech end to provide a handle. The modern gunstock shape began to evolve with the introduction of the arquebus, a matchlock with a longer barrel an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
